Andy, the conventional orchestral seating we are used to is a result of aesthetical and practical considerations, defined (and restricted) by the acoustic conditions on typical orchestral stages, the intervisbility between conductor and musicians, as well as visibility and audibility of the orchestra from the audience's POV.
Personally, I'm convinced that nothing should hinder us from turning an instrument _away_ from the conductor if it sounds better like that - now that we can. đ ... I've also tried to make this very clear in the manual (p. 51 ff):

Collected Hints for Your Daily Work with Vienna MIR Pro
Move the Instrument Icon to another position on the stage. Donât follow the visual impression of MIR Proâs Main View slavishly! If the flute sounds better when it seems to sit right between the first violins â just do it. The orchestral arrangement doesnât have to look beautiful; it should sound good.
- Rotate the Instrument Icon away from the direction that seems to be the âlogicalâ one for a real player. More often than not, a hall will react very differently when the main acoustic impact of a source changes. For example: If you need more âsplashâ for a trumpet fanfare, turn their Icons away from the Main Microphone for more reflections from the rear walls. If youâre longing for a more pronounced left-right positioning impression for a certain Instrument, turn it into the respective direction. Remember: The dry sound doesnât change [when rotated] as long as you donât switch on âDry Directivityâ in the Instrument Channel â Again: Donât be fooled by the fact that in reality the players always look at the conductor. Who knows how many times a seemingly âwrongâ orientation of an instrument on stage would actually sound better?
- Try the different Character Presets. Itâs so easy, really. We have put enormous efforts into the creation of useful, individual timbre presets for almost each and every Vienna Instrument; there are sensible general settings for most other sources, too. HINT: Although it might be tempting to use similar Character Presets (e.g. âAirâ) throughout an arrangement over and over again, it is advisable not to overdo it. The (intended) colouring could become obtrusive. Try to differentiate sounds rather than to make them sound the same.

A good example is Guy Baco's brand-new MIR Pro demo called "Paradise Express". Especially in case of the string sections, he set up his instruments within MIR very differently than I thought it would be the "proper" way. But the results prove him right: The whole piece sounds exceptionally lush and spacious.
